Comparison of Radiologists and Other Specialists in the Performance of Lumbar Puncture Procedures Over Time

Comparison of Radiologists and Other Specialists in the Performance of Lumbar Puncture Procedures... ORIGINAL RESEARCH SPINE Comparison of Radiologists and Other Specialists in the Performance of Lumbar Puncture Procedures Over Time D.R. Johnson, M.D. Waid, E.Y. Rula, D.R. Hughes, A.B. Rosenkrantz, and R. Duszak ABSTRACT BACKGROUND AND PURPOSE: Lumbar punctures may be performed by many different types of health care providers. We eval- uated the percentages of lumbar punctures performed by radiologists-versus-nonradiologist providers, including changes with time and discrepancies between specialties. MATERIALS AND METHODS: Lumbar puncture procedure claims were identified in a 5% sample of Medicare beneficiaries from 2004 to 2017 and classified by provider specialty, site of service, day of week, and patient complexity. Compound annual growth rates for 2004 versus 2017 were calculated; t test and x statistical analyses were performed. RESULTS: Lumbar puncture use increased from 163.3 to 203.4 procedures per 100,000 Medicare beneficiaries from 2004 to 2017 (overall rate, 190.3). Concurrently, the percentage of lumbar punctures performed by radiologists increased from 37.1% to 54.0%, while proportions performed by other major physician specialty groups either declined (eg, neurologists from 23.5% to 10.0%) or were largely unchanged.
